Latitude e6500 connect to TV

What kind of cable will connect my laptop to my TV so I can watch movies on the TV screen that are on my laptop? I have a new VIZIO TV. I bought a Belkin HDMI cable that fit the port on the TV but not the laptop. I am not a gamer, just a movie watcher.

The port for video on the back is called DisplayPort. You can find, online, adapters that will convert to female HDMI from the DisplayPort; you can then connect a standard HDMI cable. I'm planning on doing this myself. You can also avoid the adapter and get a special DisplayPort to HDMI cable, but they look to be quite expensive.

I don't know if anything else will have to be done after the hardware is connected. I'm gonna try it myself soon (once i get an adapter and cable) and see how it goes.

I did read something about a DisplayPort dongle (it would be a small 2-inch cable that attaches to the DisplayPort).. my E6500 did not come with one. Did yours?

personally I think Dell should have included it with the laptop, like they used to include s-video/composite adapter with Latitude series. I have been using Latitudes since C series and I see their cost cutting on every new model (now E6400). This cable cost them nothing to make, so charging $20 is outrageous IMO. Try Monoprice or elsewhere for a much cheaper deal.
